[PATCH 1/2] blk-mq: use blk_mq_put_driver_tag() to put tag

[Yufen Yu <yuyufen@huawei.com>]

Expect arguments, blk_mq_put_driver_tag_hctx() and blk_mq_put_driver_tag()
is same. We can just use argument 'request' to put tag by blk_mq_put_driver_tag().
Then we can remove the unused blk_mq_put_driver_tag_hctx().
